Etc. etc. But I think it's too simple. Non-fiction can include everything from history to philosophy. Fiction can include everything from Alice Munro to Stephenie Meyer (or Raymond Carver to Dan Brown).

I read about 60/40 nonfiction to fiction, but it's all over the place. What I really love falls broadly into "cultural studies," because I like it when people deeply analyze some aspect of our culture.

How about you?

Edit: thanks for all the feedback! It's definitely more complicated than the stereotype!
